SPINNING-RING.

Specification of Letters Patent. 1

Patented July 14, 1908.

Application filed February 9, 1907. Serial No. 356,617.

To all whom it may concern:

Be it known that I, FRED H. CHAPMAN, a citizen of the United States, residing at Groton, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful'lmprovement in Spinning-Rings, of which the following is a full, clear, and exact description.

This invention is in the nature of an improvement upon the invention of the appli cation filed January 12, 1907, Serial No. 352,007, and in common with that invention it has for its object to provide a spinning particularly for s inning cotton, wherein the tension on the tiread, as it is wound on the bobbin, is regulated automatically by gravity, so that the same tension is given whether winding on full or empty bobbins, and it is possible to wind an increased quantity of thread on the bobbins; and further, the tendency to ballooning is overcome and hence separators need not be employed.

In the present invention, there is a relatively fixed part and a movable part connected with the fixed part and to which the traveler is applied, the fiXed part being detachably connected to a holder, so that the ring as a whole may be inverted. This capacity of inversion or reversibility differs from that described in the prior application in that here the fixed part is detachable from the holder along with the movable part, and in this respect the present invention is an improvement on the prior invention. The present construction is such also that the ring is capable of use in that class of spinning frames where it is sometimes necessary or desirable to reverse the twist.

While but two specific forms of the present im rovement are illustrated and herein particu arly described, it is intended to be understood that there is full interchangeability of parts or elements of the invention between the present case and the prior case.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view, Fig. 2 is a side elevation and Fig. 3 is a cross-section of one embodiment of the improvement capable of use in spinning the reverse twist. Fig. 4 is a plan view of the holder, detached. Fig. 5 is a cross-section of the holder. Fig. 6 is a side elevation of another form of ring, with the movable part lowered. Fig. 7 is a side elevation of the last above mentioned ring with the movable'part raised. Fig. 8 is a trans verse section of the last above mentioned ring, parts shown as in Fig. 7.

1 is the holder, having the ears 2, for application to a spinning-ringrail, not shown. As shown more. particularly in Figs. 3, 4 and 5, this holder is slit at 3, so as to render it more springy, and it is also equipped with a short flange 4, of a profile substantially cor responding to the profile of the ring flange, so that the ring may be sprung upon its holder and thereby be securely retained thereon.

The fixed member 5 of the ring has the inwardly projecting flanges 6 forming halves of the runway for the traveler 7, and these flanges are arranged upon opposite ends of the member 5.

The movable member 8 has its opposite ends provided with the half-fianges 9 which cooperate with the half-flanges 6 on the fixed member to complete the runway for the traveler at opposite ends of the ring. The mo vable member 8 is applied exteriorly to the fixed member and in such way as to be freely movable up and down thereon, and this movement preferably is limited by means of one or more slots 10 in the movable member and pins 11 in the fixed member, which pins project into and engage the slots. As shown, these slots are perpendicular to the holder, and thus the movable member has simply an up and down movement or rise and fall. As a result, a ring of this construction while subserving the purposes of automatic gravity devices, is also capable of being used for a reverse twist. Furthermore, if for any reason the upper portion of the ring is or becomes defective, it may be inverted, by first removing the traveler and then springing it oil? of the holder, turning it upside down and springing it u on the holder again by its other end, an then putting the traveler in place on the thus inverted flanges. This capability of inversion or reversibility of the ring is also feasible in that form of ring where there is not only the rising and falling movement but also a circular movement, and this adaptability of the invention is illustrated in Figs. 6, 7 and 8, where the slot 12 is of lozenge or diamond form, and the pin 13 plays within er angle of this slot and on its walls to gui and falling and circular movements. These views show the movable member at two extremes of movement, which will never be reached under ordinary circumstances in spinning, because the tension of the thread on the traveler is such as to keep the movable member at such height that the pins will be in contact with one or another of the upper walls of the slots, according to the direction of movement, and, therefore, the tension will be automatically accommodated. The tension of the thread never raises the movable member so high but that the pins are in engagement with the upper walls of the slots the respective wall so engaged depending u on the direction the traveler is running. Ifbnce, one wall or another of each slot always has a bearing upon its complemental pin, and the point of bearing varies along the pin, this variation following the variation in tension of the thread. The engagement of a number of the slots and pins keeps the ring in level alinement. The form of the slots permits the circular movement of the movable member so as to shift from one side of the pins to the other and thus admit of spinning a reverse twist. Fig. 6 shows the movable member at rest upon the holder, but this is a position that will not be possible .while the traveler is in place, since the traveler itself, while engaged by the thread, will hold up the movable member, with the pin in contact with the upper walls of the slot. Figs. 7 and 8 show the same member raised into the position it may take when the thread is being hooked into the traveler, since the upward pressure of the thread under the traveler raises the movable member thus and gives room for the thread to pass into the traveler.

I have shown but one slot 10, but it is obvious that any number of slots 10 or slots 12 and complemental pins may be used. It is possible also in some classes of work to use an invertible ring of the character herein described, without the pin and slot connection,

the traveler alone forming the connection between the two members of the ring.

The advantages growing out of the use of the invention of the earlier case are common to the present invention also.

What I claim is 1. A spinning ring, having a fixed member, a holder to which it is detachably secured, and a movable member applied to the fixed member and movable longitudinally thereof, the fixed member and the movable member having arts of traveler flanges at opposite ends, wiereby the ring may be inverted or reversed, and a traveler.

2. A spinning ring, having a fixed member and a movable member applied to the fixed member and movable vertically thereon, the fixed member and the movable member having parts of a traveler flange, a traveler applied to the said flange parts and serving to control the downward movement of the movable member, and the said fixed and movable members connected by a suitable number of pins engaging perpendicular slots which restrain the vertical and horizontal movements a spring holder to which it is detachably se-' cured by springing it on and off, and a movable member applied to the fixed member and movable longitudinally thereof, the fixed member and the movable member having parts of traveler flanges at opposite ends, whereby the ring may be inverted or reversed.

5. A spinning ring, having a fixed member, a holder to which it is detachably secured,

and a movable member applied to the fixed member and movable longitudinally thereof, the fixed member and the movable member having parts of traveler flanges at opposite ends, whereby the ring may be inverted or reversed, the fixed and movable members having a perpendicular slot and pin connection, whereby the ring may be used for reverse twisting.

' 6. A spinning ring, having a fixed member and a movable member, a traveler thereon, and means whereby said movable member may obtain a limited rising and falling movement and also a limited back and forth movement upon the fixed member, the direction of the back and forth movement depending upon the direction in which the traveler spins, said traveler serving to control the gownward movement of the movable memer. I

7. A spinning ring, having a fixed member and a movable member on said fixed member, a traveler applied to both members and serving to control the downward movement of the movable member, and connections between the two members whereby the mov able member may rise and fall as the spinning progresses and may also be given a circular movement whose direction is controlled by the direction of movement of the traveler, said connections serving also to keep the movable member in level alinement and limiting its circular movement.
